ENVELOPE.

Application filed December 8, 1925. Seria: No. 72,981.

TheV present invention relates to envelopes, and aims to provide an envelope havingr novel and improved sealing meansv in order that the envelope can not be opened or the contents removed Without detection.

Another object is the provision of such an,

envelope wherein the postage stamp when applied will aid in 'sealing the envelope, thereby requiring the mutilation of the stamp ino'rder to open the envelope Without tearing' or cuttingr other portions ot the envelope. Itwis also an objectof the invention to provide an envelope of the character india rear view of the improved envelope prior to the sealing thereof.

Fig. 2 is a front view of the envelope. Fig. 3 is a longitudinal section through the seal taken on the line 3-3 of Fig. 2, with the envelope closed and sealed. Fig. 4 is a plan view of the which the envelope is folded.

The envelope is formed from a single blank 4ot' suitable paper or other material.

blank from The envelope has the front or face portion. 7

and the back portion composed of the flaps 8, 9 and 10 extending;r from the portion 7 and .folded back against the portion 7. The flap 9 overlaps the flap 8 and is attached thereto by the adhesive material 11 on the inner surface of the flap 9, and the end iap 10 overlaps the flaps 8 and'9 and has adhesive material 12 thereon causing 'the flap 10 to adhere to the 'laps and9, thereby forming the body of the envelope which is open at that end QppOSite to the end of the portion 7 to which the flap 10 is attached. The blank has gussets 13 uniting the iaps 8 and 9 with the flap 10 at the corners between them, in order to reinforce the envelope at the-correspond ing corners thereof. Thel gussets 13 are folded with the naps 8 and ,9, and With the "5 lia-p 10.

'A closure flap 14 extends from the end of the. frontportio'n 7 opposite to the flap 1 0,

and has adhesive 15 on the inner surface.

thereof to enable the flap 14 to be attached to the flaps 8, 9 and 10 in closing, the e'n-y velope. There are gussets 16` between e' the flap 14 and the aps 8 and 9 at they corners between them which are folded with the'liaps 8 and 9 and with the flap 14;v in order to reinforce and protect the corresponding corners The flap 10 is tapered and extends substantially the entire length of the envelope, While the flap 14 is also preferablytapened but is vof shorter length. p

In order to seal the envelope, the front portion' 7 is provided adjacent totheopen end or mouth of the envelope with the slots 17 over which thepostage stamp 18 is pasted on the portion 7. As shown, the' slots 17are located midway V'loetvveen the longitudinal edgesof the envelope adjacent to the tiap 151. A tongue 19 extends from the end of the flap 10 vat the open end or mouth ofthe envelope to be folded inwardlyso as to enter the pocket of the envelope behind the slots 17. .The flaps 8 .and 9, as shown, have notches 20 at the open end or-mouth of the envelope to facilitate the folding of the tongue 19 back into the envelope, and the tongue 19 is provided with adhesive .material 21 atthat side which rests against the inner surface ofthe front portion 7. The

tongue 19 is of a width to permit it to be inserted or threaded through the slots 17 if desired.

In sealing the envelope, after the letter 22 (or other contents) is inserted into the envelope, the tongue 19 is mostened, and is then folded and inserted into the envelope between the letter 22 and front portion 7, so as to adhere to the inner surfacev of the portion 7. 'The adhesive material 15 of the iiap 14 is then moistened and said flap 14 closed and attached to the back portion of the envelope. The postage stamp 18 is then pasted .on the front'portion 7 over the slots 17 so as fto'adhere to the portion 7 around the slots, here to the tongue 19 through the slots V17. 1f desired, when inserting the tongue 19 into the envelope, the tongue may be inserted and the postage stamp will also adoutwardly through the first slot 17 and then,

inwardly through the second slot, in orderv et of the envelope when theiiap 14 is closed."`

ints, Thus, the flap14 is attached to the ack rtion of the envelope, the tongue 19 extenhg from the back portion is attached to 4the front portion across the mouth or open end of the envelo e, and the postage stamp 18 is attached to t e tongue 19. Consequently, in order to open .the envelope and remove the letter or contents 22 Without outting or tearing the envelope, it is necessary to remove the stamp 18 from the tongue 19,

to remove the flap 14 from the flaps 8, 9 and f 10, ,and to remove the tongue 19 from the front portion 7. The stamp 18 adhering to the portion 7 and tongue 19 cannot be" removed vitho'ut being mutilated, so that the tampering with the stamp can be detected. Furthermore, the tongue19 cannot be de tached from the portion 7 and stamp 18 without tearing or mutilating the envelope so as to afford means of detection. Consequently, the envelope is sealed to prevent unauthorized opening of the envelope or removal of the contents without the tampering being indicated or detected. lt is apparent that even thoughthe flap 14 is loosened and opened, the contents of the envelope cannot be removed without tearing or releasing the tongue 1-9 which adheres both to the front portion 7 and to the posta-ge stamp 18.

By the provieion of the slots 17 between the longitudinal edges of the envelope, the stam 18 will be located at a position sutli'- -cient y below the upperedge of the enve- .moeten the invention, what is claimed as new isz- An envelope formed from e. single blznilt end comprising e front portion having e ep extending therefrom, e beek dep extend.-
